      <p>
            The database record format for databases containing BLOBs was
            changed in 12.1.6.0.30. Any database from version 12.1.6.0.21 or
            earlier that contains BLOBs must be upgraded before it can be
            opened by this or any later version of Berkeley DB. Databases
            from version 12.1.6.0.30 or later that contain BLOBs and databases
            without BLOBs do not require upgrading.
